We changed the way users and groups are replicated on the system (where they are used for SSH access): now the system can query the database directly. This means most account operations will be immediately effective (group memberships), while others will only have a 5-minutes delay (ssh keys updates).

There was some delays in replications for the past few days during the switch, apologizes for that - it's better than before now :) We put efforts in making sure this didn't change anything, though feel free to let us know if you suspect something is going wrong.

Technically we're using libnss-mysql-bg as well as a few new Savane scripts.
